Swedish metal legends Opeth are the special guests of this Saturday's Headbanger's Ball, which, as you probably know, airs on MTV2 at 10pm EST. Naturally, their striking video for "The Grand Conjuration" will also be featured, along with Chimaira's "Nothing Remains," and many, many more head-banging delights. So tune in and visit the Opeth Listening Lounge in case you need to get "in the mood" beforehand.
